Configuring IP Subnet VLANs
Use the VLAN > IP Subnet page to configure IP subnet-based VLANs.
When using port-based classification, all untagged frames received by a port are
classified as belonging to the VLAN whose VID (PVID) is associated with that port.
When IP subnet-based VLAN classification is enabled, the source address of
untagged ingress frames are checked against the IP subnet-to-VLAN mapping
table. If an entry is found for that subnet, these frames are assigned to the VLAN
indicated in the entry. If no IP subnet is matched, the untagged frames are classified
as belonging to the receiving port’s VLAN ID (PVID).
